Publication number: 20160277465Abstract: A method of processing real-time streaming media is performed at a computer system having one or more processors and a memory. The computer system obtains a streaming media based search request from a terminal, the search request including information from a streaming media data packet captured by the terminal. After extracting a set of streaming media features from the streaming media data packet, the computer system searches a plurality of streaming media feature sequences, each sequence corresponding to a respective streaming media source end, for a feature segment that matches the extracted set of streaming media features. After acquiring a playback timestamp of the matching feature segment and a corresponding source end identifier, the computer system searches for preconfigured interaction response information that corresponds to the acquired source end identifier and the playback timestamp and returns the corresponding interaction response information to the terminal.Type: ApplicationFiled: May 26, 2016Publication date: September 22, 2016Inventors: Jie Hou, Dadong Xie, Hailong Liu, Bo Chen
